, HOLDFAST.

-S1?ECIFIGATION forming part of Letters Patent No. 694,996, dated March11, 1902.

Application filed December 29,1900. SerialNn. 41,534. Y(No model.)

To @ZZ whom binary concern:

Beit known that I, THnonoR BoNAvnN- TURA SAUErga subject of the King ofPrussia, Emperor -ot Germany, residing at Ober- Reifenherg, in theKingdom of Prussia and German Empire, have invented certain new anduseful Improvements in Holdfasts, ot which the following is aspecification.

My present invention relates to improvements in holdfasts for pipes,dsc. and the object of my improvement is to enableV such holdfasts to bedriven into a wall or the like without danger of the holding partthereot` being broken oit or bent..

My improved holdfast comprises a hook part and a pipe-holding part.These parts are so constructed and arranged that on driving the holdtastthe holding part is only pressed against the pipe when the hook has beendriven quite into position.

In the accompanying drawings two examples of my improved holdfast arerepresented.

Figure l is a side elevation of the tubeholding part; Fig. 2, a sideelevation of the hook part, and Fig. 3 a holdfast formed byY the hookand holding part shown in Figs. l

` and 2. Fig. 4 represents'a holdfast which u form for the greaterportion of its length.

differs somewhat in construct-ion from that shown in Fig. 3. Fig. 5 isan end view of the second construction. Fig. G represents the holdingpart thereot in section, and Fig. 7 p

shows the hook and also a screw to be applied in the manner hereinafterdescribed.

M y holdfast, Fig. 3, comprises the parts o and b. The hook partaconsists of a thin [iat bar, which is tapered to a point. The head c ofthis bar is so shaped that on passing the hook through the holdingv partthe latter bears against this head. The holding part b consists of a datbar bent into a semicircular In the straight part d there is a hole c totit the upper end of thev hook. the head of the hook hasa shapecorresponding to the form of the holding part, so that the latter whenthe hook is in position is held fast. On driving the hook it is struckThe inner surface of to be easily removed from the hook at any timeafter the holdfast has been driven into position. The parts d and b ofVthis construction do not differ in exterior forni from the same parts ofthe construction described above. The slot e' in the part d of thisconstruction is made much longer than the hole e in the formerconstruction. In this construction the head c of the hook b can hepassed through the slot e' in either direction.

A hole is provided in the head c of the hook a, through which a pin orscrew o passes, and the back of the holding part presses against thispimWhile the lower end of the straight part of b bears against the headAof the hook. This construction is used as follows: After the part b hasbeen placed on the end of the hook and the screw or pin g has beeninserted the hook e is yd riven into the wall or the like until the partb incloses the pipe. If now it is desired at any time to remove thepipe, it is only necessary to remove the pin or screw g, whereupon the'part b of vthe holdtast can be easily taken ott and the'piperemoved. Anew pipe can then be fastenedinj position, if desired.

, It is of course not necessary to drive the hook, with the partbthereon, into posit-ion, as the latter can be fitted onto the former atany time after driving the hook.

What I claim, and desire to secure by Letters Patent of the UnitedStates, is 1. A holdfast comprising two parts, a hook part and a holdingpart, the hook part being adapted to be passed through an opening in theholding part, to hold the latter against the body to be supported, andthe hook part having a shoulder for engagement with the holding part toprevent dislodgment of the latter.

2. A holdfast comprising a hook part and a holding part, the holdingpart being slotted longitudinally to receive the hook part, the hookpart having a shoulder to engage the holding part, the hook ot the hookpart loeing adapted to lie with itsinner face iush with that oftherholding part, and a' screw passed through the hook part, to preventdisplacement of the holding part.

3. A holdt'ast comprising a hook part'and a pering bar having :tprojecting head, the holding part comprising a semicireular plate havinga fiat portion extended at right angles thereto and being slottedlongitudinally toA receive the hook part, the hook part having ashoulder to engage the holding part, the hook of the hook part beingadapted to lie with its inner face ush with that of the holding part,and a sorew passed through the hook part, to prevent displacement of theholding 1opart.

In testimony whereof I have hereunto set my hand in the presence of twoWitnesses.
